AMD will also offer extras with the new cards. For example, the Radeon
HD 7900 Series will feature a 'Three-for-Free' promotion that includes
three DirectX 11 titles, while the Radeon HD 7800 Series will ship
with a free copy of Dirt Showdown.

The new pricing puts AMD's graphics lineup in better position to
compete with NVIDIA's Kepler architecture. In addition, the move could
come right before another top level announcement by the company,
possibly in preparation for a dual-GPU HD 7990.
